Observations are weighted by the block-level inverse probability of treatment assignment, following Gerber and Green (2012). Below 50th/25th votes are votes in which the share of MPs voting the modal vote is less than the median/25th percentile among all votes. Compliance is the proportion of times the two MPs in a pair vote the same way in a given session. Similarity is the average vote similarity between the two MPs in a pair. Dyadic-robust p-values are in square brackets. Randomization inference p-values (1000 draws) are in curly brackets. Sharpened q-values (Anderson 2008) for non-placebo tests are in <>. Special sessions and a short session (2017) are excluded. For lead and lag specifications, sessions are also dropped where lead/lag would be a special/short session or a session in a different parliamentary term. Strata FE are dummy variables for whether both MPs in a pair were pre-assigned seats, one MP in a pair was pre-assigned a seat, or neither MP in a pair was pre-assigned a seat. Same Party is equal to one if both MPs in the pair are in the same party for that session. Outcome Mean and Standard Deviation are for the sample included in the Panel A regressions. *** p<0.01, ** p<0.05, * p<0.1.} \\ \end{tabular} }
